This means one device handles both short-circuit and overload protection for motor branch circuits, eliminating the need for a separate overload relay and contactor combination in many applications. The same 100 kA rating holds at 240 V and 500 V (cite:,). Panel integration is straightforward — the 65 mm width (cite:) fits standard enclosure cutouts, and the 97 mm depth (cite:) leaves clearance for wiring behind the device. Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire (cite:,).
Rated voltage range is 20 to 690 V. No ground fault detection. At 690 V the breaking capacity drops to 4 kA (cite:) — coordination with upstream fuses or breakers is essential for 690 V installations. The gL/gG fuse ratings at 400 V and 500 V are 32 A (cite:,), and 25 A at 690 V (cite:), defining the maximum backup fuse for the device. Mounting position is any (cite:), with minimum clearances of 50 mm upward and downward, 30 mm to the side, and 0 mm forward and backward (cite:,).
